Until recently, the recovery phase of the emergency management cycle has received relatively little attention from the natural hazards research community in comparison to the other phases of planning, mitigation, and response. However, in the prolonged aftermath of Hurricane Katrina, studies on recovery have become more common as evidence from this disaster suggests that the process is spatiall...
سال ها است که شبکه های حسگر بی سیم برای مشاهده و نظارت بر رخدادها و محیط اطراف به کار گرفته شده اند. این شبکه ها برای کاربردهای مختلفی از قبیل نظارت بر میدان جنگ، نظارت بر ترافیک، پیگیری یک هدف، نظارت بر آتش سوزی جنگل و غیره مورد استفاده قرار می گیرند. یکی از عوامل تأثیرگذار بر عملکرد موفقیت آمیز شبکه های حسگر بی سیم، پوشش مناسب محیط می باشد. میزان پوشش نیز، وابستگی شدیدی به زیرساخت ها از جمله ...
Visualizing Topography by Openness:A New Application of Image Processing to Digital Elevation Models
A new parameter, here termed openness, expressing the degree of dominance or enclosure of a location on an irregular surface, is developed to visualize topographic character. Openness is an angular measure of the relation between surface relief and horizontal distance. For angles less than 90", it is equivalent to the internal angle of a cone, its apex at a DEM location, constrained by neighbor...
Mount Everest, known locally as Sagarmatha or Qomolangma, is the world's highest (8849m), and arguably most iconic, peak. That allure draws large numbers of tourists to Nepal every year with hopes seeing climbing famed mountain. Importantly, tourist presence has wide ranging environmental (Napper et al., 2020; Aubriot 2019; Semple 2016; Faulon Sacareau, Miner 2021; Byers, 2005), cultural (Rai, ...
We suggest that ‘axial lines’ defined by (Hillier and Hanson, 1984) as lines of uninterrupted movement within urban streetscapes or buildings, appear as ridges in isovist fields (Benedikt, 1979) as Rana first proposed (Rana, 2002). These are formed from the maximum diametric lengths of the individual isovists, sometimes called viewsheds, that make up these fields (Batty and Rana, 2004). We pres...
A free Plain Language Summary can be found within the Supporting Information of this article. Today, we are facing global sustainability challenges that complex and interconnected. Human activities such as land-use change contributing to biodiversity crisis simultaneously impacting our own well-being. To address these challenges, need develop a holistic understanding multifunctional landscapes ...
There is a need in the humanities for a 3D WebGIS with analytical tools that allow researchers to analyze 3D models linked to spatially referenced data. Geographic Information Systems (GIS) allow for complex spatial analysis of 2.5D data. For example, they offer bird’s eye views of landscapes with extruded building footprints, but one cannot ‘get on the ground’ and interact with true 3D models ...
Visioning is becoming a significant way to engage communities in developing transit systems that better satisfy their wants and needs. Visioning involves a range of groups participating in a process that determines the goals and forms of transit systems and developments. Visualization is one of the most widely-used and important methods in visioning. However, while it has many strengths, visual...
The paper describes research work in the area of mobile cartography as part of IST-project WebPark. It presents the concept and development of a location based service for searching for species information in a recration area. With help of this concrete use case, questions about dynamic cartographic symbolisation of point objects can be investigated, which will be hopefully prove generic enough...
Several perspectives on the groves are briefly treated. Broader appreciation is needed of the giant sequoia groves which are not famous and easily accessible. The USDA Forest Service administers the largest single ownership of natural giant sequoia grove acreage. The giant sequoia groves have major resource values in addition to old-growth giant sequoias. Certain giant sequoias should be consid...
